2.Introduction
Avobenzone is an oil soluble ingredient used in sunscreen products to absorb the full spectrum of UVA rays. It is a dibenzoylmethane derivative. Avobenzone exists in the ground state as a mixture of the enol and keto forms, favoring the chelated enol. Its ability to absorb ultraviolet light over a wider range of wavelengths than many organic sunscreen agents has led to its use in many commercial preparations marketed as "broad spectrum" sunscreens. Avobenzone has an absorption maximum of 357 nm

4. Applications:
Avobenzone having phenyl ketone group and sterically hindered group in one molecule, is an oil
soluble sunscreen agent that absorbs a wider range of UV wavelengths. It absorbs both UV-A
(380–315 nm that is associated with long term skin damage) and UV-B (315–280 nm that causes
sunburn) rays. Avobenzone is known as one of the most effective sunscreen ingredient.
